Title: Inlet valve drive control device of internal combustion engine
Inventor: OBA HIROSHI
IPC: F02D13/02
Filed: 2003-01-28
Abstract: <P>PROBLEM TO BE SOLVED: To improve a fuel consumption at a transient time by preventing valve lift characteristics at the transient time from being separated from the best fuel consumption characteristics at a stationary time.  <P>SOLUTION: When a target torque tTe is increased by an acceleration operation, a working angle changes with a first variable valve mechanism at the early stage of the transition, and a center angle changes with a second variable valve mechanism at the latter stage of the transition. A changing speed of the working angle is increased with the first variable valve mechanism by adding a predetermined amount on the target value of the working angle when it enters a VTC control range so as not to be off ideal characteristics at the stationary time on the way to the transient change, meantime, to suspend the second variable valve mechanism. This process makes the shift of the maximum lift point approach the ideal characteristics at the stationary time.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
